4 Claims. (01. 46-4218) The invention relates to the construction ofmodels of truck assemblies for model railway cars. I

,It is-an object of the invention to produce 5 miniature or modelrailway equipment which will resemble withinuch fidelity the exteriorappear ance of full-sized structures. The small scale to whichthesemodels are reproduced and the cost entailed prohibits fastening ofthe parts in the 10 same manner as they are fastened in the'fullsizedequipments. Therefore, construction must be provided for-the modelswhich will be'relatively inexpensive but will cause the assemblies tohave the same general appearance as the cor- 16 responding full-sizedstructures.

Other objects and advantages will become apparent as the followingdetailed description progresses, reference being had to the accompanyingdrawing, wherein- 20 Fig. I is a plan view of a model truck assembly forrailway cars, which model truck assembly embodies the invention.

Fig. 2 is a side elevation of the improved model truck assembly.

5 Fig. 3 is a section taken on line 33 of Fig. 1.

Fig. 4 is a section taken on line 4-4 02f Fig. 3; and

Fig. 5 is a perspective view of a fastening or closure member whichforms part of the improved 30 model truck assembly.

Referring to the drawing, in which a preferred embodiment of theinvention is shown, reference characters 5 and 6 designate the endframes of a model or miniature truck assembly for minia- 35 ture railwaycars, the end frames 5 and 6 being connected together at their centersby a bolster I. The end frames 5 and 6 are provided with suitablerecesses 4 in their ends to receive the ends of shafts 8 and 9 whichhave car wheels 40 I mounted thereon.

The end frames and 6 and the bolster l are preferably cast from softmetal such as ordinary white metal, and are preferably cast to reproduceto scale the similar parts of full-sized structures.

45 Particular efforts are made to have the outer surfaces of theassembled model car truck appear to be true reproductions of thefull-sized structures.

When the end frames, the bolster, the shafts 50 and wheels have beenassembled, the end frames must be free to adjust themselves somewhatindependently of each other to accommodate for unevenness in the trackor surface over which the model is to move, and the end frames must be'55 held to a limited movement toward and away from-each other. pfovidtliese features, the

. invention includes novel mean ior connecting the bolster! with the endframes 5'and 6. The bol-' ster -l is formed preferably with integraltrunnions I5 which at their outer ends have integral 5 disks I6. Thedisks I6 are disposed in pocketsor recesses I? provided ininwardlyextendin in-'-' tegral lugs' I8 formed upon the end frames 5'and 6, the recesses or pockets IT being open at their upper ends untilclosed byfastening or closure 10 members I9 (Figs. 3, 4 and 5). It willbe noted tnatthe lugs I8 are provided with downwardly: extending slotsthrough which the trunnions I5 project, the construction being such thatthe trunnions may rotate in the slots 20 and are 15 slidably mountedtherein. As best illustrated in Fig. 4, each of the lugs I8 is providedat its upper end with outwardly extending beads or ribs 22 to permit theassociated closure or fastening member I9 to be attached to the lug soas to preventan accidental removal of the bolster from the associatedend frame. The closure or fastening members I9 are preferably formedfrom sheet metal which is sufiiciently elastic to permit the fasteningmembers to be snapped on and off the lugs I8. It will be noted that eachmember I9 is formed with a lip or hook 23 at one end and with a lip orhook 24 at the other, which lip 24 is provided with an extension orfinger piece 25 which may be grasped when it is desired to remove themember 29 from its lug I8. It is obvious that the lips or hooks 23 and24 may be snapped on and off the beads 22.

As best shown in Figs. 3 and 4, there is sufficient space in therecesses or pockets IT to permit movement of the bolster l upwardly anddownwardly with respect to the end frames 5 l and 6.

' When the apparatus shown in the drawing is to be assembled, it is onlynecessary to assemble 40 the wheels III with the shafts 8 and 9 and thenassemble the shafts with the end frames 5 and 6,, after which thebolster may be dropped in place between the frames and the fastening orclosure members I9 may be snapped in place. The structure is thenassembled and may be attached to a miniature car. For this purpose, thebolster is provided with a, central bore 30 to receive a king pin (notshown).

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changes,therefore in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention as broadly as possible, in view of the priorart.

I claim:

1. A truck assembly for use in the construction of models of railwaycars and the like having in combination, axles, car wheels on saidaxles, a bolster having, trunnions at its ends and said trunnions beingprovided at their outer ends with disks, end frames holding the ends ofsaid axles and being provided with recesses opening atthetop surfaces ofsaid frames for said disks and of such size as to permit the disks topass through the openings for assembly of the structure, and closuremembers removably secured across the upper faces of said recesses toprevent accidental displacement of said disks from said recesses wherebysaid bolster is secured movably between said 7 end frames.

- 2; A truck assembly for use in the construction of models of railwaycars and the like having in combination, axles, car wheels on saidaxles, a bolster having trunnions at its ends, said trunnions, havingenlarged, portions at their outer ends, end frames holding the ends ofsaid axles, said end frames having recesses opening at the top surfacesofsaid frames for said enlarged portions and having slots for rotatablyand slidably journaling said trunnions, and closure members for saidrecesses to prevent accidental displacement of said enlarged portionsfrom said recesses whereby said bolster is secured movably between saidend frames.

3. A truck assembly for use in the construction of models of railwaycars and the like having in combination, axles, car wheels on saidaxles, a bolster having trunnions at its ends and said trunnions beingprovided at their outer ends with disks, end frames holding the ends ofsaid axles and being provided with recesses for said disks, and springclips extending across above said disks for closing said recesses toprevent accidental displacement ofsaidenlargedportions from saidrecesses whereby said bolster is secured movably between said endframes, said spring clips being removably secured in position by meansof hook portions engaging beads on said end frames.

4. A truck assembly for use in the construction of models of railwaycars and the like having in combination, axles, car wheels on said 1axles, a bolster having trunnions at its ends and Y sIGUR BEUTLICH.
